RUDDER CO NNECTION.

SPECIFICATION forming part of Letters Patent No. 502,723, dat-ed Augustl S, 1893.

Applicationled February 9, 1893.

Be it known that I, ELIoT G. JACKSON, of the city of PhiladelphiaJ and State of Pennsylvania, have invented a certain new and useful Improvement in Rudder Connections for Boats; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification.

My invention has relation to rudder connections for boats, and consists in the novel construction hereinafter particularly described and claimed.

The object of my invention is to provide a rudder hinge or connection of a construction which Will enable the rudder to be readily adjusted into position upon the boat, especially when in the water; a further object is to provide a construction which will prevent the rudder from slipping out of the hinge or connection, as is very apt to occurl in other constructions of connections in small row boats in rough water.

In the accompanying drawings similar letters of reference referto similar parts throughout the several views. t

Figure l is an end perspective view of a row boat having the rudder connected thereto through the medium of my improved rudder connection. Fig. 2 is a side elevation partially in section, slightly modified. Fig. 3 is a partially sectional elevation .representing in detail the constructionshown in Fig. l. Fig. 4 represents a modied construction of the lower joint. A

A represents the rudder in position upon the stern of the boat, B. The two joint connections, C, C', are secured by screws, rivets, or by other suitable means, upon the stern, B, at the desired distance apart on a perpendicular line with each other. The lower joint, C, is constructed with an enlarged mouth preferably of a diameter about three timesgreater than the diameter of the securing pimp, which is provided upon the rudder A; the mouth, 0V gradually decreases in diameter to the bore, c', preferably provided for the lower end of the pin, p; the interior diameter ofthe-bore,V c is preferably only slightly greaterv than the diameter of the end of the pin, 10. The interior Serial No. 461,548. (No model.)

of the base of the bore, c', is preferably slightly concaved for the reception of the end ofthe pin,

The joint, C', is provided with a vertically disposed bore for the reception of the pin, p', of a diameter only slightly greater than the diameter of said pin.

It is clear from the construction described that the pin, p, may be readily inserted into the joint, C, to its proper Yposition while the -boat isin the water. -The upper pimp', being out of, or about on the water line,can be readily adj usted into .the smaller orifice of the joint, C', Without difficulty. In inserting the lower pin, p, it has only to lstrike any point within the mouth, c, when the'inclined angle of the walls of the joint, C,will guide it down to its proper position in the bore, c. I also preferably provide at the joint C, as illustrated in Figs. l and 3, a spring pawl, S, ad-

v justed in suitable bearings in the stern wall of the boat with a horizontally disposed inwardly protruding pin, s, for operating the pawl; a small spiral spring s is provided upon the pin, s, within the bearings to keep the pawl normally engaged in an inclined groove, g, p rovided in the end of the pin, 1o the angle of the groove, g, and of the end of the pawl being such, as illustrated in the drawings, to allow the pin, p', to be automatically engaged by the pawl, S, when fully inserted in the bore of the joint, C; the pawl, S, is released by withdrawing the pin, s. v

The interiordiameter of the lower end or bore, c', of the connection, C, is preferably, as before stated, only slightly greater than the diameter of the lower part of the pinup, so that when the rudder is in position the pin, p, will not wabble in the connection but will maintain a stead y pivotal bearing. The weight of the rudder is preferably sustained by the end of the pin, p, bearing upon the base of the bore, c, though a portion of the weight may be borne by the shoulder formed in the upper connection, C', as in the construction shown in IFig-1. It is also clear from the description that the connection, 0, may be circ'ularly constructed withv the interior bore, c', centrally located in the diameter bf the mouth, c, as illustrated in Fig. 4. Y

yMy improved rudderconnection described `may be used with or without the pawl device IOO shown in Figs. l and 3, though I preferably employ the same to secure therudder in position.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. In combination with the male pin of a hinge joint a joint having an opening or mouth of enlarged diameter, an interior base bearing for the end of the male pin, a reduced lower interior diameter only slightly greater than the diameter of the end of the lower portion of the male pin adapted to engage therein, the interior diameter of the said joint gradually decreasing from the mouth toward said lower bearing substantially as described.

2. In a rudder attachment for boats in combination with a hinge-joint, C', and male pins, p, p', a joint, C, having an interior base-bearing of adiameter about equal to the diameter of the lower end of the pin, p, adapted to engage therein, and a mouth of greatly enlarged diameter gradually decreasing to the basebearing substantially as described.

8. In a rudder attachment for boats in combination with the hinge-joint, C', and pins, p, p', a lower joint, C, having an interior basebearing and a lower interior bore, c', of a diameter slightly greater than the diameter of the pin, p, adapted to engage therein, and a mouth, c, of enlarged diameter gradually decreasing to the diameter of the bore, c', substantially as described.

et. In a rudder attachment for boats the combination of pin p and lower hinge-joint,

C, having lower interior bore, c and enlarged mouth, c, gradually decreasing in diameter to the bore, c', upper joint, C', having Vertical orifice provided therein, pin, p', secured to the rudder, shouldered groove, g, provided in said pin, 1J', and pawl, S, provided in a guide or casing in the stern ot the boat, B, pin, s, and spiral spring, s', engaging thereon, substantially as described.

5. In a rudder attachment for boats a funnel-shaped hinge-joint, C, hinge-joint, C', pins, p, p', provided upon the rudder engaging respectively in the joints, C, C', groove, g, provided in the pin, p', aud pawl connection adapted to engage in said groove, g, consisting of a slde-pawl, S, pin, s, and spiral spring, s', substantially as described.

In witness whereof I have hereunto set my hand-this 7th day ot' February, A. D. 1893. ELIO'F G. JACKSON.
